Electron microscope magnification Magnification is a very simple concept, but it sometimes can create confusion because of its own definition. The aim of this blog is to clarify magnification in scanning electron microscopes (SEM) and focus on other parameters which can des...
The magnification compensating device of a scanning electron microscope has refocusing means 40, 42, 46 to change beam-energy signals according to a nominal value that corresponds to the predetermined energy level. Further, magnification compensation means 50, 52 are provided which are connected to ...
A series of baseline displacement measurements have been obtained using 2D Digital Image Correlation (2D-DIC) and images from Scanning Electron Microscopes (SEM). Direct correlation of subsets from a reference image to subsets in a series of uncorrected images is used to identify the presence of ...
A combination of drift distortion removal and spatial distortion removal are performed to correct Scanning Electron Microscope (SEM) images at both ×200 and ×10,000 magnification. Using multiple, time-spaced images and in-plane rigid body motions to extract the relative displacement field throughout...

This latter is obtained by observation of flat polished sections under scanning electron microscope (SEM), using the backscattered electron imaging (BSEI) mode. The choice of the optimal magnification to get an accurate counting of the pixels identified as anhydrous cement phase is discussed in this...
The derived results show the effectiveness of the developed algorithm and also demonstrates its ability to be used in robotics as well as in material characterization under SEM. 展开 关键词: calibration drift principal differential analysis scanning electron microscope ...
of the DisclosureThe present invention relates to an apparatus for generating a magnification compensation signal for use in a scanning electron microscope. The apparatus includes an electron beam generator that generates a beam at a predetermined energy level in accordance with a beam energy signal. ...
Most of these studies, however, focused exclusively on the error rates of the microwear quantification using scanning electron microscopy (Grine et al. 2002; Galbany et al. 2005). In other studies that focused on the reproducibility and reli- ability of the low magnification wear method ...
